IMPROVEMENT lN HAND-LEVER ATTACHMENTS FOR STEAMPUNIPS.

Specification forming part of Letters Patent No. 142,562, datedSeptember 9, 1873; application filed March 3, 1873.

struction and arrangement of the detachable hand-lever attachments usedin direct-acting Asteam-pumps, for the purpose of operating such pumpsby hand in the absence of steam or other motive power usually employedfor operating such pumps, and is especially designed to be employed inconnection with the steam-pump of this class, for which Letters Patentof the United States have hereto- My invention consists in arranging thehand-lever which works the tappet-arm or piston-rod in a horizontalposition, so that a number of persons may be able to work them at thesame time.

In the hand-lever attachments heretofore used, the levers have alwaysbeen placed in a y,

also, in the cases of such pumps with perpendicular hand-leverattachments, that it is in i most cases necessary to erectplatforms'over the pumps, in order that the operative may reach suchlevers, which is not only an expensive, but an exceedingly clumsy andinconvenient arrangement.

In the drawings, Figure 1 represents a view looking down upon thesteam-pump, and showing three different ways in which the levers may beapplied. 1

A, B, and C represent the levers, extending horizontally across thepiston-rod and bed of the pump and engine, the levers AB embracing thetappet-arm D by means of a yoke or open slot in the end, as in A, ornear the center, as in B, the lever C passing through a horizontal slotin the. tappet-arm E, and all having fulcrums on a brace or support, F,extending from either side of the pump between the two cylinders. Ineach case the lever is attached at its fulcrum by means of a removablepin, or otherwise, in such a manner that it may be readily detached.

It will be seen that the lever, as arranged, may be readily reached ineach case without the'employment of platforms, and that any number ofmen may work upon them at the same time, the number being only limitedby the length of the levers.

What I claim is- The combination of the detachable handlever fordirect-acting steam-pumps, arranged horizontally between the twocylinders, and

the tappet-arm, substantially as described.
